There are as many action cameras out today as there are energy drinks, but the GoPro Hero3 Black is the hands-down best for capturing everything from stupid stunts to sensational achievements. Not only is it smaller and easier to mount, the Black also supports such best-in-class specs as the ability to snag both ultracrisp 1080p video at 60 frames per second and cinema-quality 4K resolution video at 15 frames per second. It can even snap stills while recording. The proof is in our post-test footage: The Black caught everything more clearly than its competitors. [$400; gopro.com]
